APPARATUS` FOR DISTILLING TURPENTINE.

SPECIFICATION forming part of Letters Patent No. 788,310, dated April25, 1905.

Application filed July 28, 1904. Serial No. 218,549.

To Il m7110111, it maag/"conferma:

Be t known that I, SIDNEY S. FLEMING, of lnunswick, in the county ofGlynn and State of (reorgla, have invented certain new and usefulImprovements in Apparatus for Distilling Turpentine; and I do herebydeclare the following to be a full,'clear, and exact description of theinvention, suoli as will enable others skilled in the art to which itappertains to make and use the same.

'lhe object of this invention is to provide simple and highly-eiiicientmeans for effecting the distillation of spirits of turpentine under theaction of steam and without pressure, avoiding destructive distillationand the extraction of tar and insuring the thorough penetration of themass of wood bythe steam.

'lh'e invention will be hereinafter fully set forth, and particularlypointed out in the claim.

ln the accompanying drawings, Figure 1 is a side elevation, with partsin sectionand parts broken away. Fig. 2 is a top plan view of the cover.

Referring tothe drawings, l indicates a tank or retort of barrel shape,so formed that its bottom always presents inclinations from the endstoward the center. This tank is mounted atits ends on hollow shafts 2,fitted in bearings 3, one of said shafts having a band wheel or pulley 4secured thereon. Passing transversely through one of these shafts is asteam-supply pipe 5, terminating within the tank in a perforated section6, extended longitudinally of the tank andsupported a short distancefrom the outlet end of the latter by a brace 7. Extending through theother shaft in axial line with the perforated section 6 of thesteam-pipe is an outlet-pipe 8, to the inner funnel-like end of which issecured a strainer 9. At the transverse center of the tank is a chargingand discharge opening l() normally closed by a valve or cover 12. haveshown this cover as equipped with a threaded spindle, whereon works anut 13, to which are secured several radiating rods 14,

designed to engage an upwardly-projecting rib 15 at the periphery of thevalve and extend through openings in lugs 16, on shoulders of which thevalve is designed to fit, said lugs being rigidly secured to the tanksurrounding the opening. A hand-wheel 17 is secured on the spindle, soas to permit of the latter being readily operated to release or securethe valve. '.lhe latter may, if desired, be hinged at one side.

In practice the wood, which is ground fine,- is supplied to the tankwhen the opening" thereof is at the top, the valve being removed. Thequantity of wood so supplied -will not quite lill the tank, the objectbeing to allow the wood to roll freely inside when the tank is beingrotated, with the result that the steam will pass thoroughlytherethrough at every point. In this way I avoid having to resort topressure to make the steam penetrate the mass of wood, and Ilikewiselavoid the necessity of employing superheated steam, the samelobjection applying thereto as in the use of the steam under pressure.The vapors of distillation pass off through the strainer and outlet-pipe8. When it is desired to recharge the tank or retort, the rotationI ofthe latter is stopped when the opening is at the top. The valve is thenremoved or loosened, and a series of revolutions imparted to the tank,so that the contents will readily fall therefrom each time the openingpasses downwardly. By reason of the double truncation orbarrellikeformation of the tank or retort all the contents will readily falloutwardly through the discharge-opening.

The advantages of my invention are apparent. A tanker retort constructedin accordance therewith `is extremely simple and inexpensive, and themethod employed for effecting the distillation of the wood insures thethorough extraction of the turpentine without destructive distillationof the wood and also without the necessity of employing sup'erheatedsteam. Furthermore, by reason of the tank or retort being ofdouble-truncation formation I am enabled not only to effect a thoroughagitation of the mass of wood, but also to maintain it in a loose state,so that it may be penetrated by the steam at every point.

and having a funnel-like mouth., a strainer over said mouth, and meansfor rotating the tank.

In rtestimony whereof I have signed this 15 specification ln thepresence of two subscribing' witnesses. Y

SIDNEY S. FLEMING.
